Stock Inspection & Requirements - Grizzly G0813 Owner's Manual

Stock Inspection &
Requirements
Follow these rules when choosing and joint-
ing stock:
• DO NOT joint or surface plane stock that
contains large or loose knots. Injury to the
operator or damage to the workpiece can
occur if a knot becomes dislodged during the
cutting operation.
DO NOT joint or surface plane against the
•
grain direction. Cutting against the grain
increases the likelihood of kickback, as well
as tear-out on the workpiece.
Jointing and surface planing with the
•
grain produces a better finish and is safer
for the operator. Cutting with the grain is
described as feeding the stock on the jointer
so the grain points down and toward you as
viewed on the edge of the stock (see Figure
below).
Note: If the grain changes direction along the
edge of the board, decrease the cutting depth
and make additional passes.

• Scrape all glue off the workpiece before
jointing. Glue deposits on the workpiece,
hard or soft, will gum up the cutterhead and
produce poor results.
Remove foreign objects from the work-
•
piece. Make sure that any stock you pro-
cess with the jointer is clean and free of dirt,
nails, staples, tiny rocks or any other foreign
objects that could damage the cutterhead.
These particles could also cause a spark as
they strike the cutterhead and create a fire
hazard.
Note: Wood stacked on a concrete or dirt
surface can have small pieces of concrete or
stone pressed into the surface.
Make sure all stock is sufficiently dried
•
before jointing. Wood with a moisture con-
tent over 20% will cause unnecessary wear
on the cutters and poor cutting results. Excess

moisture can also hasten rust and corrosion.
